To aZZ whom it may concern.-

Be it known that I, CLEMENT C. CLAwsoN, a citizen of the United States,residing at Newark, in the county of Essex and State of New Jersey, haveinvented certain new and useful Improvements in Tire-InflatingApparatus; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to letters ofreference marked thereon, which form a part of this specification. V

This invention, which relates to improvements in air-pump-operatingmechanism for the inflation of the tires of bicycles and other vehicles,is a division of my former application for Letters Patent forimprovements in coin-controlled air-pump-operating mechanism filed March31, 1899, Serial No. 711,193; and my present invention has for itsprimary object to provide an apparatus which can be secured to the sideof a building or upon a post and has a supporting-bracket provided withan air duct or tube which communicates with the air pump or pumps withina suitable casing of the device to enable riders of bicycles and othervehicles to place the air-valve connected with the tire of a wheel incommunication with the end of said bracket and the tube or duct in saidbracket and then inflate the tires of their vehicles by turning a crankof the apparatus and forcing the air into the tire to fully inflate thesame.

A further object of this invention is to provide an apparatus having abracket of the nature above set forth and a coin-controlledpump-operating mechanism within the casing of the device, which lattercan be freed by depositing a coin in a coin-slot to enable the turningof the crank for operating the mechanism.

My present invention therefore consists in the novel arrangements andcombinations of the various'pa-rts hereinafter set forth and in thedetails of the construction thereof, all of which will be finallyembodied in the clauses of the claim, which constitute a part of thisspecification.

The invention is clearly illustrated in the accompanying drawings, inwhich- Figure 1 is a front view of my novel construction of apparatus.Fig. 2 is an end view of the same, and Fig. 3 represents a top or planview of the apparatus, all of said figures illustrating in connectiontherewith an .arrangement of supporting-bracket which forms a part ofthis invention. Fig. 4 is a side view of the wheel-supporting bracketemployed in connection with the apparatus. Fig. 5 is a face view of oneof the bracketsections, and Fig. 6 is a horizontal cross-section of thetwo bracket-sections, illustrating one manner of securing them togetherfor the retention of an air-tube therebetween. Fig. 7 is a detail Viewof the upper and inner portion of one of the bracket-sections, with theend portion of the air-tube in position.

Similar letters of reference are employed in all of the saidabove-described views to indicate corresponding parts.

In said drawings, A designates a suitable casing of iron or wood, whichis preferably of the shape indicated in the several figures of thedrawings, but may be of any other desirable configuration, the saidcasing being provided with a back a, sides a, and a top and bottom o Thesaid back may be provided with a suitable means for attaching the casingto the side of a building or upon a post, as will be clearly evident.

The sides and the top and bottom pieces of the casing A are preferablyprovided with a suitable and ornamental molding a and a cross piece orbar which connects the two sides a of the casing A in such a manner thatan opening will be formed at the top and an opening will be formed inthe lower portion of the front of the casing. The said openings areusually formed with marginal flanges a", on which can be made to restthe doors I) and b, as indicated in Fig. 1. In the door I) is the usualform of coin-slot b and a lock 6 while the door I) is provided with alock b In suitable bearing portions in the cross piece or bar and in theback of the casing A is rotatively arranged a main shaft 0, whichprojects from the front of the said piece or bar and has a crank asecured thereto, as indicated. Within said casing A and operated fromsaid shaft 0 is an air-pump-operating mechanism of any desirableconstruction, but preferably of the construction set forthin my formerapplication for Letters Patent, Serial No. 711,193, a tube or pipe 19being connected with the pump mechanism, said pipe leading from thecasing A and being arranged between a pair of grooved plates 8 and s ofa bracket or support S. The said grooved plates 8 and s are suitablysecured together by means of screws or pins 8 and are also provided withflanges s for attaching said plates against the underside of saidcasingA by means of screws .9 orany other suitable fastening means. Asshown, the end of the tube or pipe 19 is provided with a nozzle-shapedenlargement 19 which is arranged in a socket portion 3 of a pair ofupwardly-extending parts 8 of said plates 3 and s. The tirevalve of thewheel of a bicycle or other vehicle can thus be arranged upon saidenlargement 1;, the gooseneck formed by the parts 3 serving to properlysupport the wheel, and

by operating the pump mechanism the tire can be fully inflated.

In order to protect the air-outlet in the gooseneck, an arm 25 may bepivotally arranged on a pin 75 in said bracket S, said arm having a cap25 which fits over said outlet when not in use to protect the same fromdirt, dust, or other foreign matter.

Having thus described myinvention, what I claim is 1. In combinationwith pumping mechanism inclosed in a casing, a rigid wheel-support onthe outer side of said casing, said support having a gooseneck and anopening therein, and a pipe connecting the pump mechanism with saidwheel-sup port, substantially as and for the purposes set forth.

2. In combination with pumping mechanism inclosed in a casing, a rigidwheel-support on the outer side of said casing, consisting, essentially,of a pair of grooved platess and 8, means for securing them together, agooseneck s and a pipe p arranged between said grooved plates,substantially as and for the purposes set forth. Y

3. In an air-pump-operating mechanism, the combination, with a, casingand its mechanism therein, of awheel-support on the outer side of saidcasing, having a gooseneck provided with an air-outlet, and a capremovably arranged over said outlet, substantially as and for thepurposes set forth.

4. In combination with pumping mechanism inclosed in a casing, a rigidwheel-support on the outerside of said casing, comprising a pair ofgrooved sections, a tube connected with the pump mechanism and arrangedin said grooved sections, and means for securing said sections together,substantially as and for the purposes set forth.

5. In combination with pumping mechanism inclosed in a casing, a rigidwheel-support comprising a pair of separable sections on the outer sideof said casing, said support having a gooseneck and an opening therein,and means connected with said support and pumping mechanism forconveying air from said pumping mechanism into and through said supportto the tire of a wheel on said support, substantially as and for thepur-' poses set forth.

In testimony that I claim the invention set forth above I have hereuntoset myhand this 2d day of October, 1899.
